Since the Spring Festival, many places have been in continuous rainy days, and during this time, vegetables are in the period of seedling cultivation. If the daily management is not timely, it will have a great impact on vegetable production, so today Xiaobian says that after the beginning of spring The precautions for field management of vegetable seedlings during planting are as follows.
First, strengthen the management of planting period and increase the seedling emergence rate
The melon vegetables should be kept away from the cold weather during the sowing period. The seeds should be planted in the first 3-4 days when the seeds are white and the flowers are in good weather. When planting, use heating equipment such as electric heating wire. After sowing, build a small arch shed and cover the non-woven fabric to increase the heat preservation. After the emergence of the vegetables, the suitable temperature should be lowered in time to prevent the vegetable seedlings from growing and reducing the seedling rate. Watering can use the spare water in the greenhouse, which can prevent the seedlings from catching a cold. If the vegetable has a rational disease caused by low temperature and high humidity, it is necessary to supplement the fertilizer according to the weather conditions to promote the recovery of the seedling.
Second, strengthen pest control in the seedling stage, and cultivate disease-free and strong seedlings
After the emergence of vegetables, the disease should be promptly sprayed and prevented; prevent disease such as squatting disease and blight in the seedling stage, and use the mold to spray or spray the bed; continuous rain, snow and low temperature, greenhouse The internal humidity is large, and it can be controlled in the early stage of gray mold by using boscalid, fluorobacteria and trifloxystrobin.
Third, plant management
Early greenhouse cultivation of tomato, eggplant, pepper and other solanaceous seedlings before planting, it is necessary to refine seedlings for 5-7 days to improve seedling resistance; spray broad-spectrum bactericidal insecticide before planting, and choose to move in time when the temperature is high. Planting; 7 days before transplanting, do a good job of planting sputum, watering, and then cover the mulch, shack, improve the ground temperature; after planting, pay attention to heat preservation and stain prevention, and promote the survival of seedlings. Seedlings can be replanted within 3-7 days, and then enter daily management.
